0.107.0 — lockstep on the agent-run-contract wave

The kit follows engine v0.107.0 (the mirror byte-pinned at the release SHA — resync db06db2), and the marketplace levels up around it:

• The README goes visual — every visual a gated teaching surface. An animated hero types the five doors in a loop, the loop / layers / suite / rungs strips animate the story in both themes, and nika try 01-hello now opens the first minute: offline, zero keys, a ten-second tape recorded against the released binary. The visuals are law-bound: their vocabulary is scanned, their counts derive from the bundle, their advertised nika_* names are asserted against the live wire.
• The wire probe learned the 0.107 clap form — and six shipped targets graduated their pending claims (amp · antigravity · copilot · grok · kimi · kiro): 21 binary targets against 21 matrix rows, both directions, failing loud on a parse the binary answered.
• nika doctor leads the freshness story: it names any kit lagging the binary's train and prints the exact per-client fix. wire-all.gif is re-recorded against 0.107.0 — the sweep now previews and asks before writing.
• Gate heals: the Cursor marketplace manifest joins the train, quiet doors (nika mcp · nika catalog) are probed before being judged, and two dead lessons heal to nika trace evidence and nika try.
